As nature stirs back to life, we look forward to the familiar sights and sounds of spring. The arrival of swallows and cuckoos signals a change in season. Yet, our organized human world often clashes with nature’s own schedule, especially due to climate change.
Nature doesn’t follow the neat calendar we create. Instead, it responds to temperature changes and longer days. In Ireland, these shifts provide clear signs of climate change. For example, we heard birds singing through the winter just passed, and some plants were already sprouting.
In the past, we could expect frog spawn in February and March. Nowadays, reports show it appearing as early as December in southern Ireland. This unpredictability highlights the growing impact of our changing climate on wildlife.
Every spring, the Farmer’s Wildlife Calendar tracks these changes. Organized by the National Biodiversity Data Centre and the Department of Agriculture, it invites farmers to share their observations on nature’s first signs under various categories. This citizen science project helps us understand how different species are responding to climate shifts.
Take the barn swallow, which migrates from South Africa. In 2020, observers first spotted it on March 1, but in 2021, it didn’t arrive until March 31—a significant delay. Similarly, the cuckoo, which migrates from the Congo Basin, was recorded as arriving on March 16 in 2020, but in the subsequent years, it came later, often in early April.
On a consistent note, the blackthorn tree has followed a more predictable blooming schedule, flowering between March 14 and March 20 across those years. Interestingly, even non-farmers can contribute to the online calendar, enriching our understanding of local wildlife.
In gardens, one might have spotted the vibrant siskin recently. This small finch, recognizable by its forked tail, often visits feeders when food is scarce in woodlands. With its beautiful blend of yellow and green plumage, it’s known for hanging upside down at feeders—a fun sight indeed!
According to recent research from the National Biodiversity Data Centre, over 75% of species are showing changes in their seasonal patterns. As one expert noted, “These changes reflect the urgency of climate action and the importance of observing nature.” Awareness and education on these shifts can help us protect our environment for the future.
As spring unfolds, staying alert to these signs reminds us of our connection to nature and the vital role we play in its preservation.
